ghc: panic! (the 'impossible' happened)
(GHC version 7.4.1 for x86_64-unknown-linux):
nameModule b_a2PR{tv}
While working on this project https://github.com/mightybyte/snaplet-
postgresql-simple I encountered a GHC panic. To reproduce, check out
revision 6573d4359c5cb7699c931c44ebf1bf135099f83b (currently HEAD of the
master branch), cabal install it, then go to the example directory and
build with "ghc --make Site.hs".
This has caused the crash for me on two different Linux systems with GHC
7.4.1. I realize it requires building a large number of package
dependencies, but I have no idea of how to construct a smaller test case.
It should be pretty easy to build these dependencies with cabal or cabal-
dev.
